At the northernmost edge of Equestria, just past the Crystal Mountains and on the edge of the permanent ice cap covering the Old Territories, winter has always come early and hard to the Crystal Empire. Since the downfall of Sombra and Cadance's assumption of her rightful place as Crystal Princess, she, just like the crystal ponies she leads, has had to adapt to short days and frequent storms at the bottom of the year. By now, a few winter storms seem perfectly normal.

But three blizzards in a month? Weeks before the beginning of winter? That definitely isn't normal. This winter, the Empire may be faced with more than just a few snowstorms, but instead a struggle for its very survival. As its Princess, Cadance will be on the front lines...
